Company to Help the Service Transition Command and Control Systems to More Efficiently Provide Information to Warfighters

Arlington, VA, March 4, 2010 - CACI International Inc (NYSE:CACI)
announced today that it has been awarded
one of five prime contracts to support the U.S. Navy's Space and Naval Warfare Systems Command's (SPAWAR) command and control (C2)
operations. The multiple-award, five-year indefinite delivery/indefinite quantity (IDIQ) task order contract was awarded to CACI
for a three-year base and two one-year option periods. The contract ceiling for CACI's contract is $588 million. The new award
calls for CACI to enhance the command's communications and networking systems to enable SPAWAR's end customer – the warfighter –
to gain access to mission critical information more efficiently.

This award allows CACI to offer its enterprise information technology and network services methodology to the
customer by bringing common technologies together to meet mission requirements. Work under the contract involves helping the Navy
migrate a wide array of legacy command and control applications and support tasks to a more fully integrated service approach.
This will allow for an easier, more efficient method of providing tactical data to all users, regardless of diverse formats and delivery methods.

SPAWAR is the Navy's premier Command, Control, Communications, Computers, Intelligence, Surveillance and
Reconnaissance (C4ISR) command for acquisition and life-cycle management of communications and warfare systems. Under a variety of
contracts since 1981, CACI has supported the command with solutions that include software development, enterprise resource
planning, network engineering, software testing and certification, and training. This gives CACI in-depth experience in the
client's technical environment and user requirements to support work performed under this new contract.

According to Bill Fairl, CACI's President of U.S. Operations, "We are very pleased that the Navy's Command and
Control Program Office has demonstrated its confidence in CACI's people, processes, and tools by awarding us this significant
contract to support the warfighter. It's gratifying to be recognized for our record of outstanding past performance, our
value-focused approach, and our long tradition of exceptional service to the fleet."

CACI President and CEO Paul Cofoni observed that, "With this important award, SPAWAR allows us to expand our
already significant presence in the C4ISR community and continue our legacy of technical excellence and support. Enhancing the
Navy's IT and network capabilities will play an important role in upgrading command and control operations to better serve the
needs of our operating forces as they carry out their missions around the world."
